Hi there,

I can draw a single contour line in MATLAB using

contour(z, [i i])

however,

contour(z, [i, i])

using matplotlib gives an error. In fact any plot that plots a single

line (i.e. contour(z, 1)) also gives an error as follows,

TypeError: unhashable type: 'numpy.ndarray'

How do I draw a single contour line using matplotlib?

regards,

Brendan
